An emissions control informationlabel, showing emission levels and enginespecifications, must be placed on each vehicle atthe time of manufacture.Dealer ResponsibilityWhen performing service on any 1999 and newer<strong>Sea</strong>-<strong>Doo</strong> sport boat carrying an emissions controlinformation label, adjustments must be kept withinpublished factory specifications.Replacement or repair of any emission relatedcomponent must be executed in a manner thatmaintains emission levels within the prescribedcertification standards.Dealers are not to modify the engine in any mannerthat would alter the horsepower or allow emissionlevels to exceed their predetermined factoryspecifications.VII
INTRODUCTIONExceptions include manufacturer’s prescribedchanges, such as altitude adjustments for example.Owner ResponsibilityThe owner/operator is required to have enginemaintenance performed to maintain emission levelswithin prescribed certification standards.The owner/operator is not to, and should not allowanyone to modify the engine in any manner thatwould alter the horsepower or allow emissionslevels to exceed their predetermined factory specifications.EPA Emission RegulationsAll 1999 and newer <strong>Sea</strong>-<strong>Doo</strong> sport boats manufacturedby Bombardier are certified to the EPA asconforming to the requirements of the regulationsfor the control of air pollution from new sport boatengines. This certification is contingent on certainadjustments being set to factory standards. Forthis reason, the factory procedure for servicing theproduct must be strictly followed and, wheneverpracticable, returned to the original intent of thedesign.The responsibilities listed above are general and inno way a complete listing of the rules and regulationspertaining to the EPA requirements on exhaustemissions for marine products.

Section 04 ENGINE (4-TEC)Subsection 08 (CYLINDER HEAD AND VALVES)GENERALNOTE: This procedure to be performed for eachengine.NOTE: When diagnosing an engine problem, alwaysperform a cylinder leak test. This will helppin-point a problem. Refer to the instructions includedwith your leak tester and LEAK TEST sectionfor procedures.Always place the vehicle on level surface.NOTE: For a better understanding, the followingillustrations are taken with engine out of vehicle.To perform the following instructions, it is not necessaryto remove engine from vehicle.Always disconnect the negative wire from the batterybefore working on the engine.Even if the removal of many parts is not necessaryto reach another part, it is recommended to removethese parts in order to check them.For installation, use the torque values and Loctiteproducts as mentioned. Clean threads before usingLoctite product when installing screws.When disassembling parts that are duplicated inthe engine, (e.g.: valves, bushings), it is stronglyrecommended to note their position (cylinder 1, 2or 3) and to keep them as a “group”. If you find adefective component, it would be much easier tofind the cause of the failure among its group ofparts (e.g.: you found a worn valve guide. A bentspring could be the cause and it will be easy toknow which one among the springs is the causeto replace it if you grouped them at disassembly).Besides, since used parts have matched togetherduring the engine operation, they will keep theirmatched fit when you reassemble them togetherwithin their “group”.SPARK PLUGRemovalRemove fuel rail cover from engine.Unplug the single-spark ignition coil connector onthe spark plug you need to remove.Remove the single-spark ignition coil no. 1.Clean spark plug and single-spark ignition coil areabefore disassembly.Unscrew spark plug no. 2 then use the single-sparkignition coil to take spark plug out of spark plug hole.R1503motr44A1.

Section 04Subsection 09ENGINE (4-TEC)(ENGINE BLOCK)NOTE: It is recommended to apply this specificsealant as described here to get an uniform applicationwithout lumps. If you do not use the rollermethod, you may use your finger to uniformly distributethe sealant (unlike the Dreibond sealingcompound, using a finger will not affect the adhesion).Use the silicone-based Loctite 5910 (P/N 293 800081) on mating surfaces.CAUTION: Do not use Loctite 515 or 518 to sealcrankcase. Do not use Loctite Primer N with theLoctite 5910. Using these products or non siliconebasedsealant over a previously sealed crankcasewith Loctite 5910 will lead to poor adhesion andpossibly a leaking crankcase. These products arechemically incompatible. Even after cleaning, theLoctite 5910 would leave incompatible microscopicparticles.Use a plexiglas plate and apply some sealant on it.Use a soft rubber roller (50 - 75 mm (2 - 3 in))(available in arts products suppliers for printmaking)and roll the sealant to get a thin uniform coaton the plate (spread as necessary).

Section 05ENGINE MANAGEMENT (4-TEC)Subsection 02 (OVERVIEW)MAGNETO SYSTEM ANDPOWER SUPPLYThe mag<strong>net</strong>o is the primary source of electrical energy.It transforms mag<strong>net</strong>ic field into electric current(AC).The mag<strong>net</strong>o has a 3 phases, delta wound stator on18 poles. Capacity is 380 watts.It supplies DC current to battery after being transformedby the voltage regulator/rectifier. Refer toCHARGING SYSTEM.OPERATING PRINCIPLE OFENGINE MANAGEMENTA highly advanced engine control module (ECM)has been used to ensure a high power output withcleanest combustion. The ECM calculates theproper air/fuel mixture and ignition timing for eachcylinder separately. The fuel is injected into the intakeport of each cylinder.NOTE: On the 1503, PTO and mag<strong>net</strong>o (MAG) areon the same engine side (rear). Each cylinder isreferenced as 1, 2 and 3 instead of PTO, CENTREand MAG. The numbers are stamped on the valvecover.NOTE: “ECM” stands for engine control module.“ECM” includes an ECU (electronic control unit),sensors, injectors, electromag<strong>net</strong>ic valves and ignitionsystem.AIR INDUCTIONAir for combustion is drawn directly at the front ofthe engine through one 52 mm throttle body. Theair flow is controlled by a throttle plate and an idlebypass valve respectively. The air continues throughthe intake manifold, which contains the flame arresterand goes into the cylinder head.212 3R1503motr216A152 mm THROTTLE BODY1. Idle bypass valve2.

ECM ECU on intake manifoldThe ECM ECU gets its power by the engine fuseblock which is directly powered by the battery. It isresponsible for the following engine management/electrical functions:– interpreting information– distributing information– start/stop function– timer– DESS (Digitally Encoded Security System)– ignition timing control– injection control– The ECM ECU applies the proper map (injectionand ignition) for optimum engine operation in allconditions.– engine RPM limiter– etc.The ECM ECU features a permanent memory thatwill keep the programmed safety lanyard(s) active,fault codes and other engine information, evenwhen the battery is removed from the sport boat.LMR<strong>200</strong>4_015_05_02A.FM 05-02-5
Section 05 ENGINE MANAGEMENT (4-TEC)Subsection 02 (OVERVIEW)ECM — GENERAL FUNCTIONSSafety Lanyard ReminderIf engine is not started within 5 seconds after installingthe safety lanyard on its post, 4 very shortbeeps every 3 second interval will sound for approximately5 minutes to remind you to start theengine or to remove safety lanyard. Afterwards, thebeeps will stop. The same will occur when safetylanyard is left on its post 5 seconds after engine isstopped.CAUTION: Leaving the safety lanyard on its postwhen engine is not running will slowly dischargebattery.Antistart FeatureThis system allows starting the vehicle only withsafety lanyard(s) that has been programmed to operatea specific sport boat. This functionality is theDESS system. See below for details.Digitally Encoded Security System(DESS)The following components are specially designedfor this system: Vehicle Control Module (VCM),ECM ECU, safety lanyard cap and safety lanyardpost.The safety lanyard cap contains a mag<strong>net</strong> and aROM chip. The mag<strong>net</strong> actually closes the reedswitch inside the post which is the equivalent of amechanical ON/OFF switch. The chip has a uniquedigital code.The DESS circuitry in the ECM ECU is activated atthe factory. Therefore, a safety lanyard must beprogrammed to start the engine.NOTE: Actually, it is the memory of the ECM ECUwhich is programmed to recognize the digital codeof the safety lanyard cap. This is achieved with theVCK (Vehicle Communication Kit) (P/N 529 035844). Refer to B.U.D.S. help system to programa safety lanyard.The system is quite flexible. Up to 8 safety lanyardsmay be programmed in the memory of thesport boat ECM. They can also be erased individually.NOTE: If desired, a safety lanyard can be used onother sport boats equipped with the DESS. Itonly needs to be programmed for that sport boat.When connecting a safety lanyard cap on the post,the DESS is activated and will emit audible signals:– 2 short beeps indicate a working safety lanyard.Engine starting can take place.– 1 long beep indicates a wrong safety lanyard isbeing used or that something is defective. Enginestarting is not allowed.The memory of the ECM ECU features a selfdiagnosticmode for the DESS operation. Refer toDIAGNOSTIC PROCEDURES section for more information.The memory of the ECM ECU is permanent. If thebattery is disconnected, no information is lost.When ordering a new ECM ECU from the regularparts channel, the DESS circuitry will be activated.Engine StartingIf the ECM ECU recognizes a valid safety lanyard,it allows engine to start when the start/stop switchis pressed.If start/stop button is held after engine has started,the ECM ECU automatically stops the starterwhen the engine speed reaches 1600 RPM.Engine RPM LimiterThe ECM ECU will limit the maximum engine speed.Engine StoppingThere are 2 ways to stop the engine.Press and hold start/stop switch or remove the safetylanyard cap from its post.If the engine is stopped by removing the safetylanyard, it is impossible to restart the engine asexplained in the engine starting section.If safety lanyard cap is reconnected within 15 seconds,the current supply to the engine managementis not cut and the safety lanyard will be validated.Low-Oil Pressure Warning DeviceWhen the oil pressure falls under a certain level,the ECM ECU sends out a signal for the beeperand to the warning gauge. Additionally the enginegoes into limp home mode.05-02-6 LMR<strong>200</strong>4_015_05_02A.FM
Section 05ENGINE MANAGEMENT (4-TEC)Subsection 02 (OVERVIEW)High Coolant Temperature and EGTWarning DeviceWhen the coolant temperature or the exhaust gastemperature is getting too high, the ECM ECU sendssignals to the beeper and the warning gauge.

Section 05ENGINE MANAGEMENT (4-TEC)Subsection 02 (OVERVIEW)This engine management system controls boththe fuel injection and the ignition timing.As shown in the 1503 4-TEC CONTROL SYSTEMillustration, the ECM ECU is the central point ofthe fuel injection system. It reads the inputs,makes computations, uses pre-determined parametersand sends the proper signals to the outputsfor proper engine management.The ECM ECU also stores the fault codes and generalinformation such as: operating conditions, vehiclehours, serial numbers, customer and maintenanceinformation.Electronic Fuel InjectionThe ECM ECU reads the signals from differentsensors which indicate engine operating conditionsat milli-second intervals.Signals from sensors are used by the ECM ECUto determine the injection parameters (fuel maps)required for optimum air-fuel ratio.The CPS, the MATS, the MAPS and the TPS arethe primary sensors used to control the injectionand ignition timing. Other sensors (like temperaturesensors, etc.) are used for secondary input.NOTE: The EGT, OPS and OSPS sensors do notprovide control inputs to the ECM ECU. Their solepurpose is to protect the engine components byemitting a warning signal and/or a fault code in theevent of overheating or low oil pressure or TOPSvalve fault.Ignition SystemThe ignition system is a digital inductive type. TheECM ECU controls the ignition system parameters,such as spark timing, duration and firing inorder to achieve the proper engine requirements.Ignition CoilsThree separate ignition coils induce voltage to ahigh level in the secondary windings to produce aspark at the spark plug.The ignition coils receive input from the ECM ECU.Each coil provides high voltage to its correspondingspark plug.This ignition system allows spark plugs to sparkindependently.NOTE: Ignition coil cables are not interchangeabledue to different lengths.All three ignition coils are located on the cylinderhead directly on the spark plugs.R1503motr213A1. Ignition coilsIgnition TimingThe ECM ECU is programmed with data (it containsignition mappings) for optimum ignition timingunder all operating conditions. Using engineoperating conditions provided by the sensors, theECM ECU controls the ignition timing for optimumengine operation.There is no mechanical adjustmentto perform.Knock SensorA knock sensor is mounted on the engine blockbehind the air intake manifold. It detects specificvibrations that would be typically generated by enginedetonation. If detonation occurs, the knocksensor detects this and the ECM ECU retards theignition advance temporarily (it goes in a specificmode) until detonation stops. The ECM ECU is ableto evaluate the knocking cylinder and modifies theignition advance on just the one detonating.Engine Modes of OperationThe ECM ECU controls different operation modesof the engine to allow proper operation for all possibleconditions: Cranking, start-up, idle, warm up,part load, full load, engine speed limiter, drownedengine and limp home (see below).Fuel-Flooded Engine1If engine is fuel-flooded and does not start, thisspecial mode can be activated to prevent fuel injectionand ignition while cranking. Proceed as followsto activate it.LMR<strong>200</strong>4_015_05_02A.FM 05-02-9
Section 05 ENGINE MANAGEMENT (4-TEC)Subsection 02 (OVERVIEW)With safety lanyard on its post while engine isstopped, press and HOLD throttle lever in neutralposition.Press the start/stop button. The mode is now on.Releasing throttle lever will bring back to its normalmode.If engine does not start, it may be necessary toremove spark plugs and crank engine with ragsover spark plug holes. Refer to COMPONENT IN-SPECTION AND ADJUSTMENT subsection. WARNINGWhen disconnecting coil from spark plug, alwaysdisconnect coil from main harness first.Never check for engine ignition spark from anopen coil and/or spark plug in the engine compartmentas spark may cause fuel vapor to ignite.Diagnostic ModeThe malfunctions are recorded in the memory ofthe ECM ECU. The memory of the ECM ECU canbe checked using the VCK (Vehicle CommunicationKit) (P/N 529 035 844) to see the fault codes. TheECM ECU and the VCK are able to communicatethrough a connector on the vehicle. Refer to theDIAGNOSTIC PROCEDURES section. B.U.D.S.Version 1.1 and up must be used for this system.VCM — VEHICLE CONTROLMODULEPower DistributionThe VCM distributes power from battery to all accessories.Accessories are protected by fuses integratedin the VCM. Fuse ratings are identifiedbeside their holder.If engine is water-flooded, refer to WATER FLOOD-ED ENGINE in MAINTENANCE section.Limp Home ModesBesides the signals seen above, the ECM ECUmay automatically set default parameters to theengine management to ensure the adequate operationof the sport boat if a component of the fuelinjection system is not operating properly.The following components failure will trigger a limphome mode: CTS, EGT, OPS, OSPS and TOPS.When minor faults occur, the fault and message/beeper will stop automatically, once the conditionno longer exists.Idling throttle and letting the engine return to idlespeed may allow normal operation to return. If thisdoes not work, try removing and reinstalling thesafety lanyard on its post.Depending on the malfunction, the sport boat speedmay be reduced and not allowed to reach its usualtop speed. The engine speed will be limited to 2500or 5000 RPM.These performance-reduced modes allow the operatorto go back home which would not be possiblewithout this advanced system. Refer to the DI-AGNOSTIC PROCEDURES for a complete chart.If a fault occurs and involves a limp home modeoperation, the engine management system will reduceengine RPM gradually to the proper level.F04H70A1.

Subsection 03Section 05 ENGINE MANAGEMENT (4-TEC)(COMPONENT INSPECTION AND ADJUSTMENT)COMPONENT INSPECTION ANDADJUSTMENT 0NOTE: This procedure to be performed for eachengine.GENERALEngine problems are not necessarily related to theelectronic fuel injection system.It is important to ensure that the mechanical integrityof the engine/propulsion system is present:– good jet pump/drive system operation– good engine compression and properly operatingmechanical components, no leaks etc.– fuel pump connection and fuel lines withoutleaks.Check the chart in TROUBLESHOOTING sectionto have an overview of problems and suggestedsolutions.When replacing a component, always check itsoperation after installation.Whenever sport boat is out of water and engine isrunning, ensure to supply water through the connectoron jet pump support to cool down exhaustsystem.CAUTION: Never run engines without supplyingwater to the exhaust cooling systems whensport boat is out of water.FUEL SYSTEM WARNINGThe fuel system of a fuel injection systemholds much more pressure than on a carburetedsport boat. Prior to disconnecting a hoseor to removing a component from the fuelsystem, follow the recommendation describedhere. Some hoses may have morethan one clamp at their ends. Ensure to reinstallthe same quantity of clamps at assembly.– Use the VCK (Vehicle Communication Kit) (P/N529 035 844) to release the fuel pressure in thesystem. Look in the Activation section ofB.U.D.S. WARNINGFuel lines remain under pressure at all times.Always proceed with care and use appropriatesafety equipment when working on pressurizedfuel system. Wear safety glasses and workin a well ventilated area. Do not allow fuel tospill on hot engine parts and/or on electricalconnectors. Proceed with care when removing/installing high pressure test equipment or disconnectingfuel line connections. Use the VCK(Vehicle Communication Kit) to release fuelpressure prior to removing a hose. Cover thefuel line connection with an absorbent shoprag. Slowly disconnect the fuel hose to minimizespilling. Wipe off any fuel spillage in thebilge. Fuel is flammable and explosive undercertain conditions. Always work in a well ventilatedarea. Always disconnect battery prior toworking on the fuel system. After performing apressure test, use the valve on the fuel pressuregauge to release the pressure (if soequipped).– Always disconnect battery properly prior toworking on the fuel system. Refer to BATTERYsection.When the job is done, ensure that hoses from fuelrail going to fuel pump are properly secured in theirsupports. Then, pressurize the fuel system. Performthe high pressure test as explained in thissection and pressurize the fuel tank and fuel linesas explained in FUEL SYSTEM section.Properly reconnect the battery. WARNINGVerify fuel line connections for damage andthat NO fuel line is disconnected prior to installingthe safety lanyard on the DESS post. Alwaysperform the high pressure test if anycomponent has been removed. A pressure testmust be done before connecting the safety lanyard.The fuel pump is started each time thesafety lanyard is installed and it builds pressurevery quickly.LMR<strong>200</strong>4-016_05_03A.FM 05-03-1
Section 05 ENGINE MANAGEMENT (4-TEC)Subsection 03 (COMPONENT INSPECTION AND ADJUSTMENT)To check fuel rail for leaks, first pressurize the systemthen spray soapy water on all hose connections,regulators and injectors. Air bubbles willshow the leaking area. Check also for fuel leaks orodors. WARNINGNever use a hose pincher on high pressurehoses.ELECTRICAL SYSTEMIt is important to check that the electrical systemis functioning properly:– battery– fuses– DESS– ignition (spark)– ground connections– wiring connectors.It is possible that a component seems to operatein static condition but in fact, it is defective. In thiscase, the best way to solve this problem is to removethe original part and replace it with onewhich is in good condition.Never use a battery charger to substitute temporarilythe battery, as it may cause the VCM/ECMECU to work erratically or not to work at all. Checkrelated-circuit fuse solidity and condition with anohmmeter. Visual inspection could lead to false results. WARNINGAll electrical actuators (idle bypass valve,TOPS valve, injectors, fuel pump, ignitioncoils and starter solenoid) are permanentlysupplied by the battery when the safety lanyardis installed. Always disconnect the batteryprior to disconnecting any electric or electronicparts.To perform verifications, a good quality multimetersuch as Fluke 111 (P/N 529 035 868) should be used.Pay particular attention to ensure that pins are notout of their connectors or bent. The troubleshootingprocedures cover problems not resulting fromone of these causes. WARNINGEnsure all terminals are properly crimped onwires and connector housings are properlyfastened.Before replacing an VCM or ECM ECU, alwayscheck electrical connections. Make sure that theyare very tight and they make good contact and thatthey are corrosion-free. Particularly check VCM andECM ECU ground connections. Ensure that contactsare good and clean. A “defective module”could possibly be repaired simply by unpluggingand replugging the VCM or ECM ECU. The voltageand current might be too weak to go through dirtywire pins. Check carefully if pins show signs ofmoisture, corrosion or if they look dull. Clean pinsproperly and then coat them prior to assembling asfollows:ECM ECU connectors, OPS and OSPS connectors:Apply a thin coat of DEOXIT contact lubricant(P/N 293 550 034).Other connectors: Apply a silicon-based dielectricgrease or other appropriate lubricant. If the newlyreplaced VCM or ECM ECU is working, try the oldone and recheck if it works.Ensure that all electronic components are genuine— any modification on the wiring harness maygenerate fault codes or bad operation.NOTE: For diagnostics purposes, use VehicleCommunication Kit (VCK). See DIAGNOSTIC PRO-CEDURES subsection.After a problem has been solved, ensure to clearthe fault(s) in the ECM ECU using the VCK.

Subsection 03Section 05 ENGINE MANAGEMENT (4-TEC)(COMPONENT INSPECTION AND ADJUSTMENT)Resistance MeasurementWhen measuring the resistance with an ohmmeter,all values are given for a temperature of 20°C(69°F). The resistance value of a resistance varieswith the temperature. The resistance value forusual resistor or windings (such as injectors) increasesas the temperature increases. However,our temperature sensors are NTC types (NegativeTemperature Coefficient) and work the oppositewhich means that the resistance value decreasesas the temperature increases. Take it into accountwhen measuring at temperatures different from20°C (68°F). Use this table for resistance variationrelative to temperature for temperature sensors.TEMPERATURE RESISTANCE (ohms)°C °F NOMINAL LOW HIGH- 30 - 22 12600 11800 13400- 20 - 4 11400 11000 11800- 10 14 9500 8000 110000 32 5900 4900 690010 50 3800 3100 450020 69 2500 2<strong>200</strong> 280030 86 1700 1500 190040 104 1<strong>200</strong> 1080 132050 122 840 750 93060 140 630 510 75070 158 440 370 51080 176 325 280 37090 194 245 210 280100 212 195 160 210110 230 145 125 160120 248 115 100 125CONVERSION CHART FOR TEMPERATURE SENSORSThe resistance value of a temperature sensor maytest good at a certain temperature but it might bedefective at other temperatures.

Section 05 ENGINE MANAGEMENT (4-TEC)Subsection 04 (DIAGNOSTIC PROCEDURES)VCK(Vehicle Communication Kit)The VCK (Vehicle Communication Kit) (P/N 529035 844) is the primary tool to diagnose enginemanagement and fuel injection related problems.NOTE: The VCM programmer does not work on4-TEC models.The 4-TEC requires B.U.D.S. version 1.1 or above.B.U.D.S. diskettes are available under P/N 529 035845 and CD-ROM under P/N 529 035 886.B.U.D.S. (Bombardier Utility and Diagnostic Software)is designed to allow actuators, sensors andelectronic equipment inspection, diagnostic optionsand reset such as the closed throttle and idleactuator.For more information pertaining to the use ofB.U.D.S., use its HELP button which contains detailedinformation on its functions. WARNINGIf the computer you are using is connected tothe 110 Vac power outlet, there is a potentialrisk of electrocution when working in contactwith water. Be careful not to touch waterwhile working with the VCK.IMPORTANT: When using B.U.D.S., with the 4-TECengines, ensure that the protocol “kW<strong>200</strong>0” is properlyselected in “MPI” under “Choose protocol”.When B.U.D.S. is connected with VCM and ECMECU, the status bar shows the protocol (kW<strong>200</strong>0)and a number 1 or 2 to the right. To work with thesport boat, number 2 must be displayed.Number 2 means that 2 “ECUs” are connected(VCM and ECM ECU).F18H0XAkW<strong>200</strong>0VCM AND ECM ECU ARE CONNECTEDNumber 1 means that 1 “ECU” is connected (eitherVCM or ECM ECU). Therefore, there is a problem.Check fuses and connections.F18H0WAONLY ONE “ECU” IS WORKING. THERE IS A PROBLEMIf an “X” is shown, the safety lanyard is not installedon its post or there is a problem with both“ECUs“. Ensure VCK is working properly andcheck connections on VCK and sport boat.VCK SupplyThe VCK (MPI box) can use the sport boat powerfor its supply.The safety lanyard must be connected in order touse the sport boat as a power source.If sport boat power is used, every time the safetylanyard is taken off the DESS post, the kW<strong>200</strong>0protocol will have to be re-activated.Changes in ECM ECUAnytime a change is brought in ECM ECU throughB.U.D.S., there will be an “ECM Tracking” messagethat will say “Remove key from vehicle“.When this occurs, remove the safety lanyard fromits post and wait until the message disappears (itlasts approximately 15 seconds after lanyard removal).4-TEC SYSTEM FAULT CODESGeneralkW<strong>200</strong>0The faults registered in the VCM/ECM ECU arekept when the battery is disconnected.IMPORTANT: After a problem has been solved,ensure to clear the fault(s) in the VCM/ECM ECUusing the VCK. This will properly reset the appropriatecounter(s). This will also record that theproblem has been fixed in the VCM/ECM ECUmemory.Many fault codes at the same time will likely be aburnt fuse(s).For more information pertaining to the code faults(state, count, first, etc.) and report, refer to B.U.D.S.online help.LMR<strong>200</strong>4-017_05_04A.FM 05-04-3
Section 05 ENGINE MANAGEMENT (4-TEC)Subsection 04 (DIAGNOSTIC PROCEDURES)Supplemental Information for SomeSpecific FaultsECM ECU fault codes P0601, P0602, P0604 andP605: These codes may occur in the following situations:– Electrical noise is picked up by the ECM ECU.Ensure that all connections are in good condition,also grounds (battery, ECM ECU, engineand ignition system), they are clean and welltightened and that all electronic componentsare genuine — particularly in the ignition system.Installing resistive caps, non-resistivespark plugs or knock sensor wiring/routing maylead to generate this fault code.– Electrical noise might also lead engine to occasionalcutout without generating a fault codewhen engine is restarted. When looking at thefault code, pay attention to the “count” value inB.U.D.S. A value between 1 and 9 confirms anelectrical noise problem. A value of 10 andabove will generate a fault code.– When installing a new ECM ECU. It is not properlyprogrammed from the factory. The ECM ECUmust be returned to be properly “activated”.– If everything is in good condition, try a newECM ECU.When using the service action suggested in theFault section of B.U.D.S., the system circuits arereferred as 4-23 for instance. It means Amp connectorno. 4 and the circuit wire no. 23 as found inthe wiring diagram.When they are referred as A-41, it means connector“A” on the ECM ECU and the circuit 41.TPS (Throttle Position Sensor) FaultsFaults which are reported in B.U.D.S. fall into twogroups TPS faults and adaption faults. These aredisplayed on the B.U.D.S. system as TPS OUT OFRANGE and TPS ADAPTION FAILURE.05-04-4 LMR<strong>200</strong>4-017_05_04A.FM
Section 05 ENGINE MANAGEMENT (4-TEC)Subsection 04 (DIAGNOSTIC PROCEDURES)TPS “OUT OF RANGE” FaultIt is caused by the sensor reading going out of its allowable range.

Section 06 COOLING SYSTEMSubsection 02 (CIRCUIT, COMPONENTS AND CARE)1503 EnginesCIRCUITClosed Loop SystemNOTE: These procedures to be performed on eachengine.A closed loop cooling system is utilized on the1503 4-TEC engines, which offers an efficient enginecooling while keeping dirt and salt water outof the cooling system. This system keeps the temperatureconstant and prevents internal enginecorrosion.A separate coolant expansion tank ensures thatenough engine coolant is in the circuit during anyoperating condition.The coolant flow comes from the coolant pumpimpeller into the engine block. It goes around thecylinders and straight up to the cylinder head. Asmaller quantity of engine coolant enters the engineblock on the exhaust side for additional cooling.In the cylinder head the water channels flowaround the exhaust and then the intake valve pocketsleaving the engine through a large hose. Fromthere the coolant goes back to the coolant pumphousing and depending on the engine temperature,it flows through the thermostat directly backto the coolant pump impeller, or it makes its waythrough the heat exchanger and back to the coolantpump.A smaller quantity of engine coolant is also directedthrough the oil cooler, located under the air intakemanifold, to increase cooling efficiency.A coolant temperature sensor and bleed nipple arelocated on the cylinder head of each engine.CAUTION: Never modify cooling system arrangement,otherwise serious engine damagecould occur.Pressure CapCheck if cap will pressurize the system. If not, installa new 90 kPa (13 PSI) cap (do not exceed thispressure).COOLING SYSTEM LEAK TEST WARNINGTo prevent burning yourself, do not removethe expansion tank cap or loosen the heat exchangerdrain plug if the engine is hot.Install test radiator cap (P/N 529 021 400) and hosepincher (P/N 295 000 076) on overflow hose.

Section 08 ELECTRICAL SYSTEMSubsection 02 (CHARGING SYSTEM)CHARGING SYSTEM 0NOTE: This procedure to be performed for eachengine.GENERALMag<strong>net</strong>oThe purpose of the charging system is to keep thebattery at a full state of charge.The mag<strong>net</strong>o is the primary source of electricalenergy. It transforms a mag<strong>net</strong>ic field into electriccurrent (AC).The mag<strong>net</strong>o has a 3 phase, delta wound statoron 18 poles. Capacity is 380 watts.Rectifier/RegulatorThe rectifier receives AC current from the mag<strong>net</strong>oand transforms it into direct current (DC).The regulator, included in the same unit, limits voltageat a maximum level (14.5 to 14.8 volts) to preventany damage to components.The regulator/rectifier is a 3-phase series typewhich transforms (AC) from the mag<strong>net</strong>o into (DC)to allow battery charging.BatteryThe battery is the DC source for the electric starter,the ECU/EMS and all accessories.FuseIf the battery is regularly discharged, check fusecondition.The rectifier/regulator could cause blown fuses. Tocheck, simply disconnect the rectifier/regulator fromthe circuit.If the fuse still fails, check for a defective wire.CAUTION: Do not use a higher rated fuse asthis could cause severe damage.The charging system is protected by 1 fuse (30 A)attached to the starter relay.TESTING PROCEDURENOTE: Ensure that the battery is in good conditionprior to performing the following tests. A low ordead battery will affect test results.Rectifier/RegulatorSTATIC TEST: CONTINUITYDue to internal circuitry, no static test can be done.DYNAMIC TESTCurrent TestProceed as follows:– Start engine.– Lay an inductive ammeter on positive cable ofbattery.– Bring engine to approximately 6000 RPM.Current reading should be approximately 5 amperes,depending on battery state. If not, checkmag<strong>net</strong>o output prior to concluding that rectifier isfaulty.Voltage TestProceed as follows:– Set multimeter to Vdc scale. Connect a multimeterto battery posts. Connect RED test lead topositive (+) and BLACK lead to negative (-) batteryposts.– Note the battery voltage. A fully-charged batteryshould read approximately 12.6 vdc.– Bring engine to approximately 5500 RPM.If multimeter reads over 15 volts, regulator is defective.Replace it.If the voltage reading does not rise above batteryvoltage indicated previously, the system is notcharging.NOTE: If distilled water must continually be added,it indicates an over voltage situation requiring replacementof the rectifier/regulator. If, on the otherhand, the battery does not stay charged, the problemcan come from any of the charging circuit components.If these all check good, it would be accurateto assume the problem comes from the rectifier/regulator.LMR<strong>200</strong>4-020-08-02A.FM 08-02-1

Apply a light coat of dielectricgrease on terminals.Clean battery casing and caps using a solution ofbaking soda and water.CAUTION: Do not allow cleaning solution toenter battery.Rinse battery with clear water and dry well usinga clean cloth.Store battery in a cool dry place. Such conditionsreduce self-discharging and keep fluid evaporationto a minimum. Keep battery away from dew, highmoisture and direct sunlight.During the storage period, recheck electrolyte leveland specific gravity readings at least everymonth. If necessary, keep the battery at its upperlevel line and near full charge as possible (tricklecharge).Activation of a New Battery WARNINGNever charge or boost battery while installedin sport boat.Follow battery manufacturer’s recommendations.Charging a Used Battery WARNINGNever charge battery while installed in sportboat.For best results, battery should be charged whenthe electrolyte and the plates are at room temperature.A battery that is cold may not accept currentfor several hours after charging has begun.Do not charge a frozen battery. If the batterycharge is very low, the battery may freeze. If it issuspected to be frozen, keep it in a heated areafor about 2 hours before charging. WARNINGAlways charge battery in a well ventilated area.The time required to charge a battery will vary dependingon some factors such as:– Battery temperature: The charging time is increasedas the temperature goes down. A coldbattery accepts a lower rate of charging currentthan will a warm battery.– State of charge: Because the electrolyte is nearlypure water in a completely discharged battery,it cannot accept current as well as moreconcentrated electrolyte. This is the reason thebattery will not accept current when the chargingcycle first begins. As the battery remains onthe charger, the current from the charger causesthe electrolytic acid content to rise whichmakes the electrolyte a better conductor andthen, the battery will accept a higher chargingrate.– Type of charger: Battery chargers vary in theamount of voltage and current that they cansupply. Therefore, the time required for the batteryto begin accepting measurable current willalso vary.Charging a Weak or Completely DischargedBatteryThe battery charger should have an adjustablecharging rate. Variable adjustment is preferred,but a unit which can be adjusted in small incrementsis acceptable.The battery charger must be equipped with an ammetercapable of accurately measuring current ofless than 1 ampere.Unless this procedure is properly followed, a goodbattery may be needlessly replaced.– Measure the voltage at the battery posts withan accurate voltmeter. If it is below 10 volts, thebattery will accept current at a very low rate, interm of milliamperes, because the electrolyte isnearly pure water as explained above. It couldbe some time before the charging rate increases.Such low current flow may not be detectableon some charger ammeters and the batterywill seem not to accept any charge.– Except for this particular case, set the chargerto a high rate.LMR<strong>200</strong>4-020-08-02A.FM 08-02-5
Section 08 ELECTRICAL SYSTEMSubsection 02 (CHARGING SYSTEM)NOTE: Some chargers have a polarity protectionfeature which prevents charging unless the chargerleads are connected to the correct battery terminals.A completely discharged battery may not haveenough voltage to activate this circuitry, even thoughthe leads are connected properly. This will make itappear that the battery will not accept a charge. Followthe charger manufacturer’s instruction on howto bypass or override this circuitry so that the chargerwill turn on and charge a low-voltage battery.– Since the battery chargers vary in the amountof voltage and current they provide, the timerequired for the battery to accept measurablecharger current might be up to 10 hours ormore.– If the charging current is not up to a measurableamount at the end of about 10 hours, the batteryshould be replaced.– If the charging current is measurable before theend or at the end of about 10 hours, the batteryis good and charging should be completed inthe normal manner as specified in the manufacturer’srecommendations.– It is recommended that any battery rechargedby this procedure be load tested prior to returningit to service.Battery Installation WARNINGAlways connect battery cables exactly in thespecified order, RED positive cable first BLACKnegative cable last.Proceed as follows:1. Install battery in supplied tray.2. First connect RED positive cable. Tighten nuts.3. Connect BLACK negative cable last. Tighten nuts.4. Apply dielectric grease on battery posts.5.

In cool weather, bumper rail maybe warmed too.1. Remove bumper cover no. 1 at rear of boat.2. Remove trim no. 2 from bumper rail no. 3.3. Drill pop rivets to remove bumper rail.4. Mark hole positions on body.5. Using a 4.80 mm (3/16 in) drill bit, drill a first holethrough bumper rail at any rear end. Use locatingmark as a guide and install a rivet.CAUTION: When drilling, be careful not to damagebumper rail, hull and resonators located insideengine compartment.NOTE: Check condition of silicone joint betweenhull and body. Reseal as necessary with Adseal4511 sealant (P/N 293 800 033) or equivalent withoutacetic acid vapors.6. Position bumper rail properly onto body allaround coming back to other rear end and cutexcess length if necessary.NOTE: Masking tape may be used to temporarilyretain bumper rail ahead of your work. Prior to installingtrim in bumper rail for rear corners, applyAdseal 4511 sealant (P/N 293 800 033) insidebumper rail all around boat, as shown. This is requiredso that trim properly remains attached to rail.217. Install trim using soapy water. Gently tapping trimwith a rubber hammer will help to fit trim in rail.8. Reinstall bumper cover.9. Check fit between bumper and body. Fill gapswith silicone sealant as necessary.DECAL REPLACEMENTRemovalUsing a heat gun, warm up one end of decal for afew seconds until decal can roll off when rubbingdecal edge with your finger.Pull decal slowly and when necessary apply moreheat to ease removal on the area that has to bepeeled off.If decal tears while pulling off, it has to be heatedfor a few seconds longer. If decal tends to stretchwhile pulling off, stop heating and wait a few secondsto let it cool, then peel it off.InstallationThere are 2 types of decals used on sport boats.One has a protective film on back side and theother has a protective film on both sides. They areused on 3 types of materials; plastic, gelcoat andmetal.Decals Having a Protective Film on Back SideOnlyThese decals usually contain written information(ex.: warning) and are used on gelcoat or metal.Clean surface with a good solvent such as ACRYL-ICLEAN DX 330 from PPG or equivalent (refer tomanufacturer’s instructions).Using a pencil and the new decal as a template,mark the area where decal will be located.Remove half of the decal back protective film andalign decal with marks. Start sticking it from centerand remove the other half of the film to stick itcompletely.

It also provides a protective barrieragainst water and sun. It consists of a mixture ofresin, pigment (coloring), fillers, monomers andcatalyst which is sprayed into the mold.The body and hull of the <strong>Sea</strong>-<strong>Doo</strong> sport boat areconstructed of chopped fiberglass, saturated withresin. It is sprayed on the layer of gelcoat alongwith pieces of fiberglass mat, cloth and wovenroving which are added at required areas. Thistype of construction is very accommodating forhigh quality repairs. With patience, the propertechniques and materials, a damaged area can berestored to an original finish.The content presented here is not intended to replacethe use of a complete fiberglass and gelcoatrepair manual.

Filling the CavityThe prepared surface must be cleaned with acetoneon a cloth. Use the Gelcote ® repair kit. Followthe mixing instructions in the kit when preparingthe gelcoat putty.Carefully mix the required amount while makingsure there are no air bubbles in the mixture. Witha putty knife fill the repair area, as shown in thenext photo, and cover with a plastic film to smoothsurface. Curing time may depend on temperature,amount of putty and percentage of catalyst.After 2 hours, press lightly on the surface with fingersto test the hardness. When the area becomeshard, remove the plastic film.AIR BUBBLESPossible Cause– Air pocket trapped between layers of laminateand gelcoat.1. Preparation of SurfaceRemove all of the damaged gelcoat surroundingthe air bubble with a putty knife or preferably acarbide grinding tip. Make sure all loose and weakareas are completely removed. Sand a small areaof the gelcoat surface with 220-grit sandpaper. Ifneeded, sand the cavity itself. These areas musthave a rough surface to allow the gelcoat putty tobond properly.F09L30ADAMAGED AREA FILLED3. SandingBegin block sanding the patch with 320-grit sandpaperuntil you come close to the original surface.Remove dust with a water soaked cloth and continuesanding with a 400-grit wet paper.

Buffing and WaxingBuff the surface using a heavy duty polisher witha buffing pad. Make sure the pad is free of dirt oryou may damage the gelcoat. Carefully begin buffingwith a white medium compound RM 856. Finishoff using a fine RM 852 compound.

Section 11 HULL/DECKSubsection 03 (REPAIR)BLISTERSPossible Causes– Inert catalyst.– Improper catalyst/gelcoat ratio.A blister is a visible bump on the <strong>Sea</strong>-<strong>Doo</strong> sportboat surface that may not necessarily come rightthrough the gelcoat layer. If there are only a fewblisters, you may follow the same repair procedureas for air bubbles. If they are numerous andin close concentration, you may have to spray liquidgelcoat to achieve proper repair. This procedureis covered in the next problem.CAUTION: Ensure blistered area is completelydry before attempting repairs.MINOR GELCOAT FRACTURESPossible Causes– Flexing of fiberglass laminate.– Gelcoat thickness.– Direct result of impact.In case of fractures which have not pe<strong>net</strong>ratedpast the gelcoat layer, the repair concerns thegelcoat only. If flex cracking or impact are evident,then additional reinforcement may be necessary.This subject will be covered in the next problem.1. Preparing the SurfacesSmall FracturesOpen the cracks up with a sharp triangular canopener or preferably a carbide tipped die grinder.The V groove will provide a good bonding area forthe gelcoat. With 220-grit sandpaper, sand thesides of the notched-out areas.Numerous FracturesUsing a grinder with a 24-grit disk, remove thegelcoat. Sand the edge area with 220-grit sandpaper.2. Filling the Repair AreaSmall FracturesRefer to the same procedure as in the air bubbles.Numerous Fractures Over Large SurfacePrepare the area for spray application of liquidgelcoat. Wipe down the surface with acetone.Mask the surrounding area to protect the boat fromoverspray.Mix the needed quantity of gelcoat and catalystaccording to supplier’s recommendations. Thegelcoat can be thinned with acetone up to 10%. Ifit needs more consistency you can add cabosil.Make sure that the air supply is free of oil, dirt andwater.Test spray the gelcoat mixture on paper to verifyits consistency and pattern. You may have to apply5 or 6 coats to cover the area properly. Overlapeach coat further than the last, leaving at least 30seconds between passes. Avoid trying to coat thesurface with only a few heavy coats, as this willnot allow the gelcoat to dry properly.Apply a coat of polyvinyl alcohol to seal off the airand protect the gelcoat surface from dust. PVAspeeds up the curing process because gelcoat willnot cure properly when exposed to air.3. SandingWash the polyvinyl alcohol off with water. Dependingon the size of the area repaired, you can eitherblock sand as per previous procedure or you mayuse an air sander. Sand the surface down with progressivelyfiner grits of sandpaper until the desiredfinish is achieved.4. Buffing and WaxingBuff the surface using a heavy duty polisher witha buffing pad. Make sure the pad is free of dirt oryou may damage the gelcoat. Carefully begin buffingwith a white medium compound RM 856. Finishoff using a fine RM 852 compound. While buffing,be careful not to overheat the surface.LMR<strong>200</strong>4_027-11_03A.FM 11-03-3
Section 11 HULL/DECKSubsection 03 (REPAIR)COMPOUND FRACTURESPossible Causes– Thickness of fiberglass laminate.– Direct result of impact.Compound fractures are those that have gone pastthe gelcoated surface and in through the layers offiberglass laminate. Two types of repairs have tobe performed. The first is to restore the structuralintegrity of the damaged area. Fracture types canvary from a simple crack to a large hole. Usually,fiberglass reinforcement becomes necessary, especiallyif the fracture can be attributed to weakness.The final part of the repair is the gelcoating,which cannot be applied until the interior and exteriorlaminate surfaces have been repaired.OutsideRemove the damaged gelcoat and fiberglass witha 24-grit disk using a power sander. Grind outwardat least 2 inches from the fracture to allow thepatch to bond to strong material. Cut enough piecesof fiberglass mat necessary to build up the area.The pieces should be cut so they overlap each otherby at least half an inch. For a smoother finish,the last layer should be fiberglass cloth. If the fractureis small enough all you may have to do is fillthe area with an epoxy filler.InsideFor the interior repair, you can grind more. This willallow for more fiberglass material which willstrengthen the area. If the fracture opening is toolarge after surface preparation, you may need abacking support to cover the opening. Cut alternatingpieces of fiberglass mat and cloth in overlappingsizes.Using a clean paintbrush, brush the mixed resin onthe surface. Place the smallest piece of mat overthe fracture and then wet out the mat. Follow withthe remaining pieces of mat and final layer of cloth.While wetting the pieces make sure you work theair bubbles out and saturate all the pieces evenly.Try to work quickly, you may only have 15 or 20minutes. You may clean the brush with acetone.Wait until the repair has hardened before movingon to the interior repair. If the size of the openingis too large for the pieces to maintain the propershape, you will have to use a backing support. It isa shaped piece of cardboard that fits flush to theinterior surface and has a plastic layer on the repairside. It is held in place by tape or a support.InsideWipe down the area with acetone on a cloth. Applythe same procedure as for outside repair whenlaminating the alternating pieces of fiberglass material.If a backing support was used, remove itbefore starting the repair. After the area has hardened,remove sharp edges of material from surface.If required paint the surface.SandingOutsideThis surface will have to be prepared for applicationof gelcoat. The size of the area will determi<strong>net</strong>he gelcoating procedure to be used. Refer to therepair procedure for minor gelcoat fractures.Buffing and WaxingRefer to the buffing and waxing for minor gelcoatfractures. If painting the exterior is preferred, referto PAINTING subsection.Patching the Repair AreaOutsideThe outside should be done first. Wipe clean thearea with acetone on a cloth, then mask off area.For a small crack use an epoxy filler in the sameway you would use Bombardier gelcoat repair putty.When laying up a larger area you will use mat,cloth and fiberglass resin and hardener. Use aclean container to mix the resin, mix only what youwill need. Follow the recommended catalyst ratio.11-03-4 LMR<strong>200</strong>4_027-11_03A.FM
